The only black Republican Party district chairman in Arizona resigned from his post in the wake of Saturday's shooting, citing threats from the Tea Party faction and concerns for his family's safety.

Republican District 20 Chairman Anthony Miller was not the only party official to resign following the shooting that killed six and wounded 14 others, including Rep. Gabrielle Giffords (D-Ariz.) and a federal judge.

"I wasn't going to resign but decided to quit after what happened Saturday," he said. "I love the Republican Party but I don't want to take a bullet for anyone." Read the full story as reported in the Arizona Republic.
